Locknife / kitchen knife set


It is very dangerous if children play or use knife when adults are absent. As children do not have the ability to fully control the knife, they are always hurt by the knife. The problem is more serious if children push the knife shelf off the table with the falling knives. The knife can only be pulled out if user’s gripping power reaches the set value of the mechanism. Children do not have the competent power to unlock the knife. The lock mechanism can stable the knife inside, which prevents knife from falling down when the shelf is pushed off the table
